    What acts as preservative in this formula of a big brand anti-dandruff shampoo? Maybe Climbazole - Salicylic Acid?

    Benzyl Salicylate is essentially a component of the fragrance in the formula, and not a preservative. The anti dandruff agents seem to double up as preservatives and maybe one or two of the extracts too may help in preservation here.

    Salicylic acid would take care of bacteria, if added at 0.5% and the pH is less than 4.  The glycols help reduce water activity. The EDTA also helps the preservative. The inci name “Parfum” could be naticide or p-Anisic Acid/Dermosoft® 688 eco.

    First, it appears to me as if the ingredients list is out of order, because I don’t think that CAPB would be lower in the list than, say, hydrolysed wheat protein! It appears to be a SLES/CAPB surfactant mixture so I would expect the CAPB to be at least 10% of this product while the wheat protein would likely be 1% or 2% at most.

    Secondly, regarding preservatives, Propolis extract is a known antiseptic product and preservative (how to incorporate what is basically an oil soluble resin in a shampoo isn’t something I would like to tackle, though).
    Climbazole is an anti-fungal which might (I really don’t know) offer preservation against common things like A.Niger. I suspect (without Googling it) that the essential oil of cedar may also offer antibacterial/antifungal activity.

    I think salycilate derivatives has antibacterial characteristic and anionic surfactant has too

    The ingredients list is from the official site of the brand. Thank you all for your responses.

    So, they’re using the properties of propolis, a bee-produced resin, in this. I experimented with propolis, but I found the solubility problems were enough to put me off using it. Usually it’s supplied as a tincture with an alcohol base.
